Abstract
Ultra-fine zinc oxide powders were prepared using ultrasonic method at 60°C with zinc acetate, zinc nitrate and potassium hydroxide solution as precursors. The obtained powders were characterized by means of scanning electron microscope, thermogravimetric analysis, X-ray diffraction and infrared spectroscopy. The crystal structures were investigated based on Rietveld method. The results showed that, zinc oxide powders have hexagonal structure (P6 3mc) with particle size in the range of 100-300 nm. The mechanism for the ZnO formation was discussed. The properties of synthesized materials were examined by UV-Vis spectrum and cyclic voltammetry measurement.
